摘要:
Disclosed are a multilayered power inductor, including: a body in which a plurality of magnetic layers formed with inner electrodes are stacked; and a plurality of gap layers, wherein the plurality of gap layers are formed so as not to contact external electrodes formed at both sides of the body, and a gap composition of the multilayered power inductor. In addition, as the gap composition, the exemplary embodiment of present invention can prepare tetravalent or tetravalent dielectric oxide into the paste type and applies the gap layer structure thereto, thereby facilitating the structural design and the thickness control of the gap layer as compared with the case of forming the gap layer in the sheet shape of the related art and improving the DC-bias characteristics by maximally suppressing the diffusion with the body.
